The Spectral Energy Distribution of the High-z Blazar Q0906+6930
Abstract
We describe further observations of QSO J0906+6930, a z=5.48 blazar likely to be detected in γ-rays. New radio and X-ray data place significant constraints on any kiloparsec-scale extension of the VLBA-detected jet. Improved optical spectroscopy detects absorption from an intervening galaxy at z=1.849 and raises the possibility that this distant, bright source is lensed. We combine the new data into an improved spectral energy distribution for the blazar core and comment on the Compton keV-GeV flux component.
